Simulation of an Index-Guided Tapered Laser
应用文章
This application note shows how to model a high-power, index-guided tapered laser diode using Keysight's Tapered Laser Utility, which combines BeamPROP and LaserMOD in a self-consistent 3D simulation. Learn how tapered laser diodes offer a low-cost solution for generating high-power, coherent beams, with applications in telecom, printing and medicine. They improve beam quality compared to broad area lasers but are more complex to design due to the tapered geometry.
In this asset, explore an example that demonstrates how the Tapered Laser Utility can be used to simulate a generic tapered laser structure. The simulation setup includes both straight and tapered waveguide sections, a multi-layered epitaxial cross-section and a voltage sweep across a range of operating points. Results highlight important characteristics such as the far-field shape and beam stability, and effects like filamentation that may appear at higher powers.
The Tapered Laser Utility enables designers to accurately simulate performance and optimize their structures for high output power and improved beam quality, making it a valuable tool for next-generation laser development.
